Actually, you better change 'expr_if.hpp' as well (just in case). I think that
will fix all of the library constructs.

// remove the inclusion of <boost/preprocessor/detail/cat.hpp>

// change BOOST_PP_EXPR_IF to this:


But I think that user code might still run into this type of problem--so I think
that all the BOOST_PP_DETAIL_CAT2 (etc.) changes should be rolled back so at
least the library is ready for it.
